The Yokomo Y4-S6A Shock Cap and End Set fits the YD-4 big bore shock family and offers options to tune damping and feel. It is aimed at drivers who want straightforward adjustments to shock behaviour.
The set includes two cap choices so you can tailor valve characteristics to smoother or firmer responses depending on track type or terrain.
Shock ends are supplied to accept standard 4.3mm balls as well as larger BD7 series balls, making it easy to switch ball sizes and test handling differences.
You get four shock caps and four shock ends in the kit, enough to service all four shocks of your YD-4. The complete set simplifies upgrades and routine maintenance sessions.
